18QHTF21-43.001-OE

Oscillators Overview

The 18QHTF21-43.001-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 43.001 MHz and utilizes LVCMOS output logic. The device requires a supply voltage of 1.8V and features an enable/disable control function. It is housed in a compact 4-SMD, No Lead package, designed for surface-mount applications.

Oscillators Feature Summary

• Standardized LVCMOS output signal generation
• External control signal enables or disables the oscillator output

Oscillators Applications

• General purpose clock signal distribution
• Digital system timing references
• Embedded electronics requiring precise frequency sources

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before ordering. Confirm that the 1.8V supply voltage aligns with your power management scheme. Ensure the 4-SMD no-lead package dimensions fit within your PCB layout constraints. Check for any specific reflow soldering profile recommendations provided by the manufacturer to ensure reliable assembly.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside a precise 43.001 MHz reference. The enable/disable feature allows for power management in battery-operated devices. Consider the small form factor of the 4-SMD package for space-constrained designs. Verify compatibility with LVCMOS input stages of the target microcontroller or FPGA.

Oscillators Part Context

This part belongs to the Mercury Electronics XO series, which focuses on standardized oscillators. The model number indicates the specific frequency and voltage configuration. Mercury Electronics has a long history in quartz crystal manufacturing, providing frequency control products since 1973. This series is designed for reliability in various electronic applications.

Oscillators Replacement Considerations

Direct replacements must match the 43.001 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD package. Cross-referencing with other manufacturers' catalogs for identical specifications is recommended if availability is an issue. Ensure pinout compatibility for direct substitution.
